Question
The puzzle that we _________ today was quite a hard
_______ to crack. Directions (111-115): Each question below has two blanks, each blank indicating that something has been omitted. Choose the set of words for each blank that best fits the meaning of the sentence as whole.Solution
We can always ‘solve’ a puzzle and therefore comment that it was a hard ‘nut’ to crack . (as famously used)
If (sin A + 2cos A) = 4 cos (90° - A), then find the value of cot A.
- If cos A = √3/2, then what will be the value of tan² A?
If cos 2A = 1, then find cos A
- If sin (2A − 3B) = (1/2) and cos (A + B) = (√3/2), where 0° < A, B < 90°, then find the value of ‘A’.
Solve for 0° ≤ θ ≤ 360°:
2 sin²θ + 3 sinθ − 2 = 0
If 6sin²x + 2cos²x − 3 = 0, then find the value of sinx, given that 0° < x < 90°.
- In a triangle ABC, if 5∠A = 3∠B = 15∠C, then find the value of cosA + sin(C + 25 ° )
In ∆ABC, AB = 5cm, BC = 6cm and AC = 10cm then find out the value of cos A?
